Floribunda rose plant named ‘JACpolpa’

ABSTRACT

A floribunda rose plant having compact, upright growth; dark green, glossy, disease resistant foliage; and medium size pink flowers having a citrus fragrance presented in large clusters.

The present invention relates to a new and distinct variety of rose plant of the floribunda class which was originated by me by crossing the variety JACship (U.S. Plant Pat. No. 7,948), with the variety JACpat (not patented).

The primary objective of this breeding was to produce a new rose variety having the vigorous, upright growth and dark green, glossy, disease resistant foliage of the female parent, combined with the compact growth, larger flowers, and large clusters of the male parent. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinquish it from its parents, as well as from all other varieties of which I am aware:

1. Dark green, glossy foliage;

2. Good disease resistance;

3. Compact, upright growth;

4. Medium sized flowers presented in large clusters; and

5. Fragrance.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cutivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) colour chart, except where ordinary dictionary significance of color is indicated.
